Today lets tackle a familiar data clean-up problem using Excel – Transposing data.

That is, we want to take all rows in our data & make them columns. Something like this:

Transpose a table of data using Excel Formulas - How to & Tutorial

The easy solution – use Paste Special > Transpose

Long time Chandoo.org readers already know this. Excel has a built-in feature that lets you transpose data with a single click.

  1. Just select your original data
  2. Press CTRL+C to copy
  3. Go to an empty area and open Paste Special (CTRL+ALT+V)
  4. Select Transpose.
  5. Done!

Although this approach works, it creates a copy of your original data. So whenever original numbers change, you must waste precious key strokes & time re-doing the transpose. This is exactly the opposite of awesome.

So, lets move to formulas.

Formula Solution #1 – Using INDEX & Helper cells to transpose a table

Lets say, we have named our original data as myData

Lets also say myData has 6 rows & 7 columns. That means, the transposed table will have 7 rows & 6 columns.

  1. Create a 7×6 grid in your worksheet
  2. About this, write numbers 1 to 6 (cells D20:I20).
  3. Similarly, write numbers 1 to 7 beside it (cells B23:B29).
  4. Now use INDEX formula to transpose data like this:
  5. =INDEX(myData, D$20, $B23)
  6. Copy this formula all over and you are done!

See the illustration below to understand how this works.

Transpose data using INDEX formula & Helper cells

Formula Solution #2 – Using INDEX formula & no helper cells

Sometimes, we cannot really use a helper column. That brings us to our next solution.

In above solution, the helper cells are giving us running numbers from 1 to 6 (and 1 to 7). We can use ROWS() and COLUMNS() formulas to generate these running numbers.

So our new formula will be

=INDEX(myData, COLUMNS($D20:D$20),ROWS($B$23:$B23))

Once you write and copy paste this formula, it will automatically supply the required numbers to INDEX formula and does the magic.

How does it work?

Well, that is for you to figure out. See this illustration to get started.

Formula Solution #3 – Using TRANSPOSE formula

Do you know there is a formula that does all of this. It is called – TRANSPOSE !!!

What is TRANSPOSE formula?

TRANSPOSE formula takes a range of values (or an array) and transposes them and returns another array.

Since this formula always returns an array, we cannot use it in one cell. But we can select a range of cells & then write TRANSPOSE in them and press CTRL+SHIFT+Enter to get the values transposed.

See this demo:

Awesome, isn’t it?

How do you transpose your data?

I prefer using INDEX with ROWS & COLUMNS approach. This is very versatile & elegant. Also this approach lets me extract only a small window of large data set (by offsetting row & column numbers with something like scroll-bar position).

What about you? Which formulas do you use to transpose your data? Please share your tips & ideas using comments.

    I think the virtue of pie charts is precisely that they are difficult to decode. In many contexts, you have to release information but you don't want the relationship between values to jump at your reader. That's when pie charts are most useful.

  2. Martin says:

    Chandoo,

    millions of ants cannot be mistaken.....There should be a reason why everybody continues using Pie charts, despite what gurus like you or Jon and others say.

    one reason could be because we are just used to, so that's what we need to change, the "comfort zone"...

    i absolutely agree, since I've been "converted", I just find out that bar charts are clearer, and nicer to the view...

    Regards,

    Martin

    Chandoo -
     
    You ask "Can I use an alternative to pie chart?"
     
    I answer in You Say “Pie”, I Say “Bar”.

  5. Karl says:

    This visualization was created because it was easy to print before computers. In this day and age, it should not exist.

  6. DMurphy says:

    I think the 100% Bar Chart is just as useless/unreadable as Pies - we should rename them something like Mama's Strudel Charts - how big a slice would you like, Dear?
    My money's with Jon on this topic.

  7. Mark says:

    The primary function of any pie chart with more than 2 or 3 data points is to obfuscate. But maybe that is the main purpose, as @Jerome suggests...

  8. Chandoo says:

    @Jerome.. Good point. Also sometimes, there is just no relationship at all.

    @Martin... Organized religion is finding it tough to get converts even after 2000+ years of struggle. Jon, Stephen, countless others (and me) are a small army, it would take atleast 5000 more years before pie charts vanish... patience and good to have you here 🙂

    @Jon .. very well done sir, very well done.

    good points every one...

  9. Tim Wilson says:

    I've got to throw my vote into Jon's camp (which is also Stephen Few's camp) -- bars just tend to work better. One observation about when we say "what people are used to." There are two distinct groups here (depending on the situation, a person can fall in either one): the person who *creates* the chart and the person who *consumes* the chart. Granted, the consumers are "used to" pie charts. But, it's not like a bar chart is something they would struggle to understand or that would require explanation (like sparklines and bullet graphs). Chart consumers are "used to" consuming whatever is put in front of them. Chart creators, on the other hand, may be "used to" creating pie charts, but that isn't an excuse for them to continue to do so -- many people are used to driving without a seatbelt, leaving lights on in their house needlessly, and forwarding not-all-that-funny anecdotes via email. That doesn't mean the practice shouldn't be discouraged!

  11. Good article. Is it possible to do that with line charts?
